TOaZZ whom it may concern:

Be it known that l, FRANCIS L. BAns'roW, a citizen of the United States,and resident of Appleton. in the county of Outagamier case. Loading ofthe tank is also facilitated. Y

Figure 1 of the drawlma's represents a partly sectional elevation of apaper-stock treating apparatus comprising my improvements, together withan adjacent track structure ane a rtruck thereon, the plane yof thesectionl being indicated by line 1 1 in Fig. 2, which Fig. 2 representsa partly sectional plan view' indicated by line 2 2 in 1, parts of theapparatus lbeing removed. Fig. 3` represents a fragment of the apparatusaforesaid partly in section on the` plane indicated byline 3 3 in Fig.2; Fig. 4t, a cross-sectlonfof a-detail of said apparatus on the planeindicated by line 4 4 in.

Fig. 1; Fig. 5, a plan viewof a detail of the same apparatus partly inhorizontal section on the plane indicated by line 5;.-75 in Fig. l; Fig.6, a sectional view of another detail of the apparatus, the sectionbeing` in.- dicated by line 6-6 in Fig. 7, which Fig. 7 is viewindicatedvby` line 7-7 inFig. 6.

Referring by numerals to .the drawings, 8 indicates a cylindricalsoak-tank set to eX- tend above and below a Hoor-line 9.,` the bottom ofthe tank being provided with a depending central stuing-box 10 in whicha hydraulic plunger 11 is guided, the plunger being operated from acylindery (not` shown)- below said tank. Y y

Bolted in connection'witlr an upper outer flange of the plunger is thespiderA 12, of the apparatus, and fast on ksaid spiderfover the arms ofthe same, are I-beams, 13 upon which to support vertical division plates14 having sides thereof provided with uppercand lower right-anglestiffening-barsl, 16. Laid in on the lower stiEening-bars 16 of the'y,division plates are' perforated sector plates 17, and thesesector-plates in the arrangement specified are sections of whatconstitute the false-bottom of the tank.

.Supported in connection with the spider is the upwardly extendingcentral circulating-pipe 18 of the apparatus. This pipe has a foot 19provided with a bottom opening through which lthe discharge-endof asteam-supply pipe 20 extendsy when said spider and parts therewitharerun down in the tank, and said'opening is of suflicient area to admitthe .digesting liquor with which-paper-stock in said tank is treated.

Attachedv to the upper end-lof the circulating pipe 4are theV usualbrackets 21 to f which a conical deflecting hood is fastened,

and in connection with the hood are. brackets 22 supportinga horizontalplate23 having a keyhole-slot therein,`as isbest-shown in Fig. 5, thisslot being for registration` with a collar andbit stop 24C fast on a rod25 depending from a lever 25 in connection with the operating-valvemechanism: of the apparatus.K

yThe division plates 14 are rivetedl in slotted stay-arms 26 of collars26 thatare slipped on thecirculating-'pipe 18, and a stay ring 27 issimilarly secured to the y11p-r per stiffening-bars 15 of said plates.

Onefof a series ofguide-strips 28 is shown inthe tank for'engagernentwith a recess 29 v in thespider to-prevent said-spider and partstherewith -from turning whenV run down The guide-strips aref shorterthan those usually employed, `so-'that the spider may be elevated abovethel same forrotation, and, unless said spider is in correct positionfor lowering, the slot in the plate23 will be out of register with thestop 24 on the rod 25', to prevent operation." of the aforesaid-Vabre-mechanism. f

Boltedf to the tank,-outside of the and at suitable intervals of itscircumfersame i ence, are flanges 30 of counter-boredbosses 30 havingbayonet-slots 30, and the boss# carrier, but one of the arms and theslot for avoid by providing for making the cake in sition shown in Fig.1, the carriers 31 are moved inward against spring-resistance toposition the anti-friction rollers 33 under said spider, and the arms ofsaid carriers are adjusted in bayonet-slots of the bosses 30 to preventretraction of the carriers. The anti-friction rollers in the positionlast described prevent tilting of the spider when some of the loadthereon is' removed.

The spider being elevated as herein shown and described, portions of thecake of paperstock may be removed with the perforated sector-plates 17,onto the platform 'of a truck or other conveyance, said spider beingintermittently rotated to bring the several sections of said cake toposition for removal. As shown in Fig. l, each of the sector-plates maybe provided with a studt for connection with means Vfor withdrawal ofsaid plate and a section of cake thereon.

- For de-inkingV old papers,lthe advantages of a soak-tank arewell'known to paper makers, but heretofore the expense of handling thestock in loading and unloading operations has been diiicult andexpensive, be-

cause of not dividing` the cake-elevator of such a tank intocompartments having removable bottoms. Heretofore the expense ofhandling the stock has been considerable because of the necessity ofbreaking up the cake of de-'inked paper-stock by digging said cake apartand pitching the particles thereof into boxes on conveyer-trucks,something I division plates intermediate'of said false bot- Y tomsections.

- and removable sections of the false-bottom of the tank laid in onstiffening-bars of said plates.

` '3. A paper-stock soak-tank having I-beams mounted on arms of theelevator-spider thereof, division plates supported on said beams, andremovable sections of the falsebottom. of the tank arranged between thedivision plates.

4. A paper-stock soak-tank having the cake-elevator thereof providedwith upwardly extending division plates between which to arrangeremovable sections of the false-bottom of the tank, a circulating-pipewith said elevator, and collars on the pipe having stay-arms attached tosaid plates.

5. A` paper-stock soak-tank having the cake-elevator thereof providedwith ,upwardly extending division plates, upper and lower stiffeningbars attached to sides of the plates, a stay-ring attached tothe-uppermost of the stilfening bars, the circulating pipe with saidelevator, and collars on the pipe having stay-arms attached to saidplates, said lower stiffening bars being for the support of removablesections of the false-bottom of said tank.

6. A paper-stock soak-tank having the cake-elevator thereof providedwith upwardly extending division plates between -which to arrangeremovable sections of the false-bottom of the tank, a hooded circulatingpipe with the elevator, a guide in the tank for registration with arecess inthe spider of said elevator, a horizontal plate supported overthe hood ofsaid pipe and provided with a keyhole slot, and avalvecontrol rod having a collar and bit stop thereon registrable withsaid slot whenk saidk guide andy recess are in register. f

7. A paper-stock soak-tank having the cake-elevator thereof rotatablewhen run up and divided into compartments of which the bottoms areremovable, and retractive anti-tilt stops for said elevator in itsposition aforesaid.l n

8. A paper-stock soak-tank having the cake-elevator thereof rotatablewhen run up' and divided into compartments of which the bottoms areremovable, hollow outer bosses on the tank, a spring-controlled carrierin y each boss havingan arm engaging a bayonet slot with which the bossis provided, asupport with the carrier, andan anti-friction roller onthe support to be shot into said tank under said elevator in theposition aforesaid.

f 1n testimony that I claim the foregoing 1 havehereunto set my hand atAppleton in thecounty of Outagamie and State of Wisconsin in thepresence of two witnesses.
